I’m not entirely sure the lifespan of spider mites after no plants are in sight. I do know they can linger and no matter how good you think you got them it’s really critical moving forward you adopt a ipm product(s) and rotate it weekly for insurance. I used to spend hours(still do) bleach wiping, tearing down lights, fans, wiping down every nook and cranny multiple times determined to not see mites on my next run only to find them. Partially because I kept things perpetual. I take cuts and continue clones in a veg area for the next run.
Without seeing how wide and heavy your infestation is I would assume there is a quality of the buds taken away. The flower I grow now mite free has way stronger terps, taste, and density. Your harvest will be fine. If you took a scope to your buds later you may find mite carcasses. I was smoking mite damage for awhile lol! At least it’s not PM. And even outdoor has some degree of pests damage. The mites are only after the chlorophyll in the leaves. Harvest/Cure as usual. I didn’t conqueror mites until I started using PureCrop1 and a Dr.Bronner(peppermint) ipm spray and rotate them every 4 days for a few weeks. I would wait until 30minutes before lights out and have to pull each plants and spray each one bottom to top on both sides of the leaves etc. and not skip a spray. I did this for 3 weeks straight. I ended up going into flower with no mites and haven’t seen them since. It’s been almost a year since. Now I spray once a week up until week 3 of flower then let it ride with no pests.
